Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4578, here are decompositions:
- 11 + 4567 = 4578
- 17 + 4561 = 4578
- 29 + 4549 = 4578
- 31 + 4547 = 4578
- 59 + 4519 = 4578
- 61 + 4517 = 4578
- 71 + 4507 = 4578
- 97 + 4481 = 4578
Showing the first eight; more decompositions exist.
